Mike Tyson and a photographer won't face charges after their scuffle last month at Los Angeles International Airport, city prosecutors said Thursday. The decision prompted authorities in Arizona to say they won't pursue any probation violations against Tyson in a 2007 drug case. Los Angeles prosecutors found insufficient evidence to charge Tyson or photographer Tony Echeverria after they were arrested on Nov. 11, spokesman Frank Mateljan said. Echeverria said a blow by the former heavyweight champion knocked him to the ground, and he was treated for a cut on his forehead. Tyson was traveling with his family when he was mobbed by photographers. His attorney Shawn Chapman Holley said at the time that Tyson was protecting his infant daughter after Echeverria collided with her stroller. The lawyer said Thursday the city attorney's office made the right decision.
